Elena, one of the biggest things that butterflies like is milkweed.
For more butterfly-attracting flowers, here is a list put out by the Farmer's Almanac:

I noticed that lavender is on the list, so I might see if the goldfinches left any seeds on my lavender bushes for me to collect. I'm also going to try and collect seed from my shasta daisies and see if I can get some snapdragon seed from my neighbor. I never did end up planting all of the floss flower I got from a previous swap, so I might offer some of what I have left of that, too.
Edited to add: oh, and there will be daylily seeds in there, too. I should have quite a few this time around!
